We didn't exactly get the most in-depth look at it, but Microsoft has just teased a few new features that you'll be able to find in the new Windows 8.1 Maps app. That includes 3D imagery that'll allow for more realistic virtual flyovers of cities (no word on specific cities that will be covered, though), as well as what looks to be a slew of additional information about cities and buildings that will be built into the app -- letting you ask questions like "Who is the architect?," for instance. You can get a quick taste of what that will look like in the gallery below.
